58:3Those who estrange their wives by equating them with their mothers, then go back on what they said, must set free a slave before they may touch one another. To this you are exhorted, and God is well aware of what you do.

58:4But whoever cannot find the means must fast for two consecutive months before they may touch one another. And if he is unable, then the feeding of sixty needy people. This, in order that you affirm your faith in God and His Messenger. These are the ordinances of God. The unbelievers will have a painful punishment.
